Question

Find the hcf of 52and 117 and express it in form 52 x + 117y. Prove that x2 - x divisible by 2 for all positive integer x

Answer 1

Step-by-step explanation:

117=52×2+13

52=13×4+0

here 13 is the HCF

we have to express 13 in form of 52x+117y

117=52×2+13

13=117-52×2

13=-2×52+1×117

x=-2 and y=1
